Titan in three different wavelenghts: the monochrome Titan (1)
|
Caption NASA originale:"This image composite was created with images taken during the Cassini spacecraft's closest flyby of Titan on April 16, 2005. Cassini's cameras have numerous filters that reveal features above and beneath the shroud of Titan's atmosphere.
This monochrome view shows what Titan looks like at 938 nnmts, a near-infrared wavelength that allows Cassini to see through the hazy atmosphere and down to the surface. The view was created by combining 3 separate images taken with this filter, in order to improve the visibility of surface features. The variations in brightness on the surface are real differences in the reflectivity of the materials on Titan. North on Titan is up and tilted 30° to the right".
